What should I wear for these tempatures?

I am going to Palm Beach on Friday and I am not so sure what I should pack. Of course I have been in warm weather before but I never seem to get it perfect. The range of temperatures including night will be about 55-82 degrees F. I am going for 7 days.

What should I pack in my suitcase to simply put it?

By the way, I am a girl.

Warm weather destinations are great, because you can pack lighter than winter weather destinations. I'd suggest the following:
- 2-3 shorts or capri pants -- basic colors such as tan, black, white work best, since you can re-wear with different tops
- 1-2 pairs of pants / jeans -- for night time and the plane ride
- 7 shirts -- I hate re-wearing, especially if you get sweaty or spill something
- 2-3 dresses or skirts/tops -- something nice to wear to dinner
- underwear / bras / socks -- as you like
- 1 nice sweater or pashmina to wear over the dress, might be chilly on the way to dinner
- 1 basic sweater to wear over your daytime clothing, in case it gets chilly or rainy
- 1 pair of flip-flops, 1 pair of walking shoes, 1 pair of dressy shoes
- 2-3 bathing suits and a cover-up -- might be a bit chilly, but best to be prepared,even if you just want to sit by the pool
- a backpack (or the like) for touring and a small evening bag for dinner
- Sunglasses and sunblock
- Toiletries, brush, etc.
- Whatever jewelry you'd like
- A book or magazine to read + maybe an iPod

You should pack some summer clothes like shorts, capris and tank tops but also pack pants and maybe a few sweater or sweatshirts

take some shirts and and jeans some capris and some long take about two sweaters one warm and one just for chili days
pack a swimsuit and sunglasses and a umbrella i live in florida so be expected for anything
